Nemůže být chyba třeba v kombinaci se souborem httpd-xampp.conf kde je
<IfModule mod_rewrite.c>
RewriteEngine On
# Redirect /xampp folder to https
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} xampp
RewriteRule ^(.*) https://%{SERVER_NAME}$1 [R,L]
# Redirect /phpMyAdmin folder to https
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} phpmyadmin
RewriteRule ^(.*) https://%{SERVER_NAME}$1 [R,L]
# Redirect /security folder to https
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} security
RewriteRule ^(.*) https://%{SERVER_NAME}$1 [R,L]
# Redirect /webalizer folder to https
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} webalizer
RewriteRule ^(.*) https://%{SERVER_NAME}$1 [R,L]
</IfModule>
